Though desktop 3D printers are a relatively new method of manufacturing, you might argue that they’re already at a plateau. You can print cute figurines, teacups that might have a leak, and sometimes replacement parts for certain objects, such as gears — not the most useful items in the world. However, what if you were able to 3D-print an invisibility cloak? Researchers at Duke University have done just that.

New findings published by quantum scientists in Germany could pave the way towards computer chips that use light instead of electricity to control their internal logic. Where today’s silicon-based electrical computer chips are capable of speeds in the gigahertz range, the German light-based chips would be some 1,000,000 times faster, operating in the petahertz range.
